Abstract: An island type mobile communication arrangement is disclosed. A plurality of BTSs connected to BSCs are reassigned as island BTSs and connected to an island BSC, the island BSC is connected to an island MSC. When entering or leaving the scope of the island MSC, a cellular phone performs a location updating procedure, and thus the island type mobile communication arrangement can provide a special service to all cellular phones in a particular local area by reading MSISDNs in an island VLR corresponding to the island MSC.

Abstract: Disclosed is a metal golf club head with optimum macro- and micro-structures and properties and a method for manufacturing a metal golf club head. The method comprises forging precisely a metal billet at a temperature between 35-47% of the melting temperature into a net or near-net lower portion shape comprising a face portion, a hosel portion, and an integrated sole and wall portion. The forging process is preferably performed in at least two stages, with the top stage forging a pre-form shape approximately equal to 60-80% of the final shape. The second stage of the forging process results in the net or near-net shape with only localized conditioning by machining or grinding. A crown portion is manufactured by stamping or forging, and then welded to the lower portion to form the metal golf club head.

Abstract: A wafer transfer apparatus adapted to a wafer ball placement apparatus including at least one wafer cassette, a flux dispenser unit, a ball placement unit, a reflow oven unit, and an unloader. The apparatus is also adapted to a wafer bump printing apparatus including at least one wafer cassette, a bump printing unit, a reflow oven unit, and an unloader. The apparatus includes a robot arm for picking up a wafer from the at least one wafer cassette and transferring the wafer to/from one of the wafer cassette, the flux dispenser unit, the ball placement unit or bump printing unit, and the reflow oven unit. The apparatus may also include a stage for carrying and moving the robot arm. With the apparatus, it is possible to reduce process time, simplify steps of transferring the wafer and lower risks of breaking wafer. The invention can achieve the effects of improving the production efficiency, saving the space and simplifying the apparatus.

Abstract: A near-net shape titanium club face for a metal wood golf head is manufacturing with improved product structure and performance. More specifically, the invention provides a metal wood golf club head face consisting of layers of grain fibering by controllable grain flow along face-orientation and surface contours, similar to composite structures, for improved directional strength, impact strength and toughness, as well as hitting face thickness design flexibility for improved hitting sound and increased coefficient of restitution without sacrificing face performance and durability. The hitting face is made by precision hot-die forging in closed dies through large (&agr;+&bgr;) forge deformation to net or near-net shape from a &bgr;-treated work piece. Alternatively, the process may be applied to aluminum alloys or steels.
